' SKI FASTENING Filed Dec. 14, 1957 Patented May 4, r1948 Application December 14, 1937, Serial No. 179,754 In Austria February 5, 1937 Section 3, Public Law 690, August 8, 1946 Patent expires February 5, 1957 4 Claims. (Cl. 28B-11.35)

This invention relates to a control device for ski -fastenings by which the heel pull member whi-ch forms a closed loop may be tensioned and released as required.

The control device according to the invention has two hooks for alternatively anchoring the heel pull member.

The invention further provides a control device for this purpose comprising an anchorage member, a lever pivoted to the anchorage member, a, hook for engaging the heel pull member resiliently connected to the anchorage member, and a hook also for engaging the heel pull member pivotally connected to the lever.

The arrangement enables a diagonal pull vto be -changed over to a normal pull simply by opening the lever of the control device. When the control lever is thus operated the hook of the control lever releases the cable, which thenceforth is engaged by the resilient hook only, which, owing to its springiness, enables the shoe heel to be lifted off the ski to a greater extent, as is required at normal pull. If subsequently diagonal pull is again to be set, it is merely necessary to close the control lever so that the second pull member Wi-ll also be engaged by the hook thereof.

The invention further comprises the provision of separate means on the aforesaid control device which enable the latter to be finely adjusted to be able to adapt the fastening to the size of the shoe used and to the desired tension.

In the accompanying drawing an embodiment of the invention is illustrated by Way of example.

Figure 1 shows the control device in side elevation and Figure 2 in plan.

Referring to the drawings, here a slideway 22 having inwardly extending ilanges 23 is secured to the ski 24 and guides the U-section slide 25, on the block 26 of which a tensioning lever 21 is pivotally mounted. A pull element I2 pivotally connected to the lever 21 is formed with a hook I3 at its free end, which is capable of engaging a yoke I5 attached to the cable V31. Further, the slide Ill has mounted thereon a hook I4, which is slidable in the longitudinal direction of the ski and the movement of which in the direction of the shoe is damped by a spring |4| disposed within the slide.

If diagonal pull is required the tensioning lever 21 is brought to the closed position 21 with the hook I4 engaging the cable 31 and the hook I3 on the pull member I2 engaging the yoke |5 (position I3', I2', I5 respectively). If, however, for example when climbing up a hill, normal pull is required, the tensioning lever is opened whereby the hook I3 on the pull element I2 releases the yoke I5 and therewith the cable 31', so that the latter is only held by the resilient hook I4, whereby it becomes possible to lift the heel of the shoe much higher.

Adjustment of the slide 25 in accordance with the size of the shoe and the tension required 1s eiected with the screw bolt 3|. The screw bolt 3| is pivotally mounted on a pin 32 in the slide 25, so that said screw bolt is rockable in a vertical plane. The slideway 22 has upbent sides 34 at its rear part, which have inwardly extending flanges or lugs 35 at their rear ends.

These flanges engage in an annular groove 33 at the nut 36, which is thus held in a freely rotatable but axially non-slidable manner by the flanges 35. Owing to the pivotal connection of the screw bolt 3| to the slide 25, it is possible to lift slightly the nut 35 with the bolt 3| for the purpose of easier manipulation.

What is claimed to be new is:

1. In a ski fastening wherein a heel pull member forms a closed loop capable of being tensioned and released, a control device comprising an anchorage member, a lever pivoted to the anchorage member, a hook for engaging the heel pull member resiliently connected to the anchorage member, and a hook also for engaging the heel pull member pivotally connected to the lever.

2. In a ski fastening wherein a heel pull member forms a closed loop capable of being tensioned and released, a control device comprising a fixed guide, a slide adjustable in the guide, means releasably locking the slide in adjusted position, a lever pivoted to the slide, Va hook for engaging the heel pull member resiliently connected to the slide, and a hook also for engaging the second pull member pivotally connected to the lever.

3. In a ski fastening device wherein a heel pull member forms a closed loop capable of being tensioned and released, a control device comprising a fixed guide, a screwed nut rotatably mounted by the guide, a slide in the guide, a bolt extending rom the slide into engagement with the screwed nut whereby rotation of the latter adjusts the position of the slide, a lever pivoted to the slide, a hook -for engaging the heel pull member resiliently connected to the slide, and a hook also for engaging the heel pull member pivotally connected to the lever.

4. In a ski fastening wherein a heel pull member forms a closed loop capable of being tensioned and released, a control device comprising a 'xed guide, a screwed nut rotatably mounted by the guide, a slide in the guide, a bolt extending from the slide into engagement with the screwed nut whereby rotation of the latter adjusts the position of the slide, a lever pivoted to the slide, a hook for engaging the heel pull member resillently connected to the slide, and a hook also for engaging the heel pull member pivotally conneeted to the lever.
